Two NICs tale of terror unfolds in the dark corners of the system.
Two NICs tale of terror unfolds in the dark corners of the system.
Hello and thanks for reading! PC NIC 1 (onboard) = 2.5 GB (directlink unraid) NIC 2 USB = 1 GB (tried 2, one realteck, one linksys) - internet NAS (unraid) NIC 1 (onboard) = 1gb - internet NIC 2 = 2.5 gb- direct link PC LAN internet is /24 192.168.1.x (multiple devices, some static, some not) direct link is /24 10.0.0.x The issue stands like this. If on the PC, windows 11, i disable the "internet" nic, the USB one, the transfer is as expected 220-240 mb, but if the USB internet NIC is on, it caps between 20-40 mb. I`m 100% the "internet" NIC is at fault, because i was transfering to the Unraid to 30-40 mb, and once i disabled the USB NIC it skyrocketed to 230-240 mb Does anyone on this planet know how and why activating the secondary NIC throotles down the direct link NIC ?
If there are multiple routes leading to the same device through various IP addresses, you must indicate the server's IP rather than its name. Referring to the name would rely on the NIC linked to the Internet, which is treated as the default gateway. Even though 20-40MB/s is on the lower end for Gigabit connections, it's still worth noting.
The problem lies in the fact that even though you have several NICs, it appears you're using one network (like 192.168.1.0/24). Your question is: If both devices are on the same local network and connected to the internet via a switch, why do you need separate Internet NICs and UnRAID connections? It might be because your setup doesn't include a switch with 2.5GbE ports. You could verify that the Internet NIC is prioritized as the top option and set up a static route for your UnRAID server's IP address. The route should point to the correct interface, which is your high-speed connection.
It seems they definitely have another connection between the two points. If their only goal is to obtain shares for this network, then none of my previous advice is needed.
